SELF-ENERGISING SENSOR

WIPO Patent Application WO2004065908

A3

The invention relates to a sensor, self-sufficient in energy, for recording physical environmental parameters, comprising at least one sensor element, a storage element and a control circuit. A timer circuit, activated by the achievement of a given electrical voltage on the storage element, activates the sensor and the control circuit at given time intervals and deactivates the same after a given operating time such that a time duration for a sensor operation and for a sensor operation pause are achieved.
